Products appear on multiple orders in a batch of orders. I created a totals
query with the fields, ProductID and SumOfQuantity. I have a TblProduct table of
products with the fields ProductID, Inventory, and other fields not relevant
here. My intent was to join the query and the table on the ProductID fields in
an update query to update Inventory by [Inventory] - [SumOfQuantity]. The update
query turned out to be not updateable.
I need ideas on another approach to update inventory from sales on multiple
orders.
Thanks!
